Meaning of Entrusting a Weapon

After drawing the Bow of Warding continuously, Reirin falls unconscious. Reirin awakens to see Tousetsu, who has caught onto the swapping of the Maidens. Around the same time, Keigetsu realizes that a curse was placed on a gift given to her. Meanwhile, at the Maiden Court, a tea party is being held in celebration of “Reirin’s” recovery. There, Kenshuu reminisces about her days as a Maiden that she spent together with Shu Gabi, the Noble Consort.
